Abstract : Second-echelon interdiction is closely tied to the close-in battle. In reality, it is part of the integrated battle which says that all means are used to fight the battle at all distances. The objective of this research effort was to examine what effect the combination of air sorties and Army missiles would have against a motorized rifle division (MRD) moving on a hypothesized three-route march. A portion of a selected East German road network was chosen as the hypothesized area through which an MRD would be traveling on its way to a release point. A model of a MRD broken down into 44 units was constructed using the SLAM computer simulation language. Units were broken down to battalion size, with a few exceptions. A flight of two aircraft is used to interdict the road on which convoys are traveling. Once a convoy is blocked by the air strike, a retargeting is conducted against the convoy using a generic Army missile loaded with wide-area anti-armor munitions (WAAM). Both the sortie interdiction and missile attack were modeled explicitly using Monte Carlo simulation. (Author)
